ROBERT LIVINGSTON, OF NEW YORK, N. Y.

TOBACCO-PIPE.

Specification forming part of Letters Patent No. 52,302. dated January30, 1866; .antedated January 18, 1866.

To all Iwhom it may concern:

Be it known that I, ROBERT LIVINGsToN, of New York, in the county andState of New York, have invented, made, and applied to use certain newand useful improvements in the construction and operation of pipes forsmoking, as also cigar-holder, and I dov declare the following to be afull, clear, and correct description of my improvements, reference beinghad to the accompanyin g drawings, making part of this specifieation,and to the letters ot' reference marked thereon, in which drawingsseveral modes of carrying out my improvements are shown.

ln the drawings like parts of the invention are indicated by the sameletters of reference.

The nature of my invention consists in so constructing the stem, tube,or mouth-piece of smoking-pipes or cigar-holders that the orifice in thesame at its opening shall be turned down so that the saliva (which inordinary pipe-smoking passes directly from the mouth of the smoker intothe main tube or stem, and thencei to the tobacco, dampening the sameand clogging the main tube or stem) is eompelled to ascend this orificebefore it ean enter the main stem or tube.

To enable those skilled in the arts to make and use my improvement, Iwill proceed to describe the same.

Many ways of efecting the object of the present invention may beemployed. In the drawings several ways are fully illustrated.

In Figure l an ordinary pipe-stem is shown adapted to effect the result.A shows the stem or tube, the central opening or orifice in which isclosed by the insertion of a movable plug, B, thus preventing the salivafrom passing from the mouth of the smoker into the stem A. This stem Ais provided on its under side with an opening placed a short distancefrom its upper end, into which opening I insert a short supplemental orauxiliary tube, U, placed vertically or at a proper angle to 'the stemA, so that while the smoke passes freely through this auXi-liary tube Oit is impossible for any saliva from the mouth of the smoker toenter'the stem A through the same.

In Fig. 2 my improvement is shown constructed in another manner andinserted in the end of an ordinary pipe-stem or nouthpiece.

In Fig. 3 the stem and auxiliary tube, properly shaped, are made in oneVand the same piece.

In Fig. et the improvement, forming a continuation of the stem andattached thereto, is shown.

In Fig. 5 the supplemental or auxiliary tube is inserted in the upperside of the main stem Aor tube and is curved sufficiently to effect thedesired result.

In Figs. 5%- and 6 still further modifications of the inventionareshown.

In. Fig. 7 (two views) a continuation of the stem, tube, or nouth-pieceis shown, formed of two plates with a central opening through w'hicl themain tube or its connection passes.

Figs. S and 9 show still further modifications of the invention.

In Fig. 10 a modification of the invention applicable to the commonclay-pipe is illustrated, the same consisting of a rubber tube made orprovided with a supplemental tube passed or stretehed over the upper endof the pipe.

The difficulties in pipe-smoking which are intended to be overcome bythe present invention are the passage of saliva from the mouth of thesmoker down the main stem or tube to the tobacco contained in the bowl,d'ampeuing the tobacco and clogging up the main stem or tube. This, asalready described, is effected by constructing the tube or stem in sucha manner that the orifice in the same at its opening shall be turneddown, so that the saliva cannot enter the main stem or tube, as it mustfirst ascend the turned portion of the stem or tube.

The presence of the movable plug B in all other instances shown, save inFig. 1, in which instance it is employed for the double purpose ot'closing the orifice and allowing the stem to be cleaned, enables thestem or tube in which it is inserted to be readily cleaned by removingthis plug B and inserting any convenient device withinthe tube A throughthe opening closed by the plug when the pipe is in use.

In several of the views shown it will be observed that the peculiarposition of the sup In combination with the stern A, closed as plementaltube insures the retention of the shown, the tube O, or its equivalent,for the pipe in the mouth of the smoker more readily purpose specified.than in the case of the ordinary pipe, as no compression of the teethupon the sten or ROBT.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
